1b=60,a=1,c=61

解答

1 b = 60, a = 1, c = 61

a = 1, b = 60, c = 61

求解步骤

1 \cdot b = 60 a = 1 c = 61

[1 \cdot b = 60 c = 61]

化简

[b = 60 c = 61]

[c = 61]

方程组的解为:

a = 1, b = 60, c = 61

3 x + 4 y = 11, 5 x - 2 y = 1

3 x + y = 2, 4 x - 2 y = 5

5 x + 4 y = 1, 2 - 5 x + 4 y = 12

2 \cdot 2 x - 3 \cdot 1 + 3 \cdot 2 = 0, 0.4 x + y - 88 = 0

2 x + 7 y = 17, 5 x + 3 y = - 1
